Customer Reviews

For the most part I was expecting to lose some accuracy when I conducted this bill for a SBR. That was definitely not the case. The price was very attractive and the quality was by far the most surprising for the price tag. I received it in the mail and quickly assembled parts together to produce a great little platform. The accuracy of the rifle is what I expect from aero precision. I would have to say that you cannot go wrong picking one of these up for yourself. (Posted on 5/4/2017)
